No, there is not. And I don't think there is an easy way to implement that either. But, the fix is just as easy as the workaround: just regenerate the CRL, with a more correct nextUpdate value. If you don't want your CRLs expire, just put that value far enough into the future. -Steffan ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
